3. Energy cannot be created or destroyed, although in many processes energy is transferred to the environment as heat. As a basis for understanding this concept:
3.a Students know heat flow and work are two forms of energy transfer between systems. 3.b Students know that the work done by a heat engine that is working in a cycle is the difference between the heat flow into the engine at high temperature and the heat flow out at a lower temperature (first law of thermodynamics) and that this is an example of the law of conservation of energy. 3.c Students know the internal energy of an object includes the energy of random motion of the object’s atoms and molecules, often referred to as thermal energy. The greater the temperature of the object, the greater the energy of motion of the atoms and molecules that make up the object. 3.g Students know how to solve problems involving heat flow, work, and efficiency in a heat engine and know that all real engines lose some heat to their surroundings. Investigation and Experimentation 1.a Select and use appropriate tools and technology (such as computer-linked probes, spreadsheets, and graphing calculators) to perform tests, collect data, analyze relationships, and display data. 1.d Formulate explanations using logic and evidence 1.k Recognize the cumulative nature of scientific knowledge 1.m Investigate a science-based societal issue by researching the literature, analyzing data, and communicating the findings. Chemistry 2. Biological, chemical, and physical properties of matter result from the ability of atoms to form bonds from electrostatic forces be¬tween electrons and protons and between atoms and molecules. As a basis for understanding this concept 2.a Students know atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds. 2.b Students know chemical bonds between atoms in molecules such as H2, CH4, NH3, H2CCH2 , N2, Cl2, and many large biological molecules are covalent. 3. The conservation of atoms in chemical reactions leads to the prin¬ciple of conservation of matter and the ability to calculate the mass of products and reactants. As a basis for understanding this concept: 3.a Students know how to describe chemical reactions by writing balanced equations. 3.g Students know how to identify reactions that involve oxidation and reduction and how to balance oxidation-reduction reactions. 8. Chemical reaction rates depend on factors that influence the frequency of collision of reactant molecules. As a basis for understanding this concept 8.c Students know the role a catalyst plays in increasing the reaction rate. |

| 2 | Reading & PowerPoint : ICE Animation” slides 1 - 4 | Pass out the 4 stroke engine animation reading. Show the PowerPoint animation of the 4 stroke engine: a longer playing version of the animation can be found at RKM.com Another animation and reading of how the internal combustion engine works can be found at How Stuff Works |
| 3 | Reflection and standards connections | Each student should write a short description of what happens at each of the 4 strokes. Show PowerPoint through ICE efficiency: Slides 5 - 6. Where does the $$ go? Video: How Stuff Works If the standards are not posted have students write a description of how the internal combustion engine demonstrates the standard Energy cannot be created or destroyed, although in many processes energy is transferred to the environment as heat. |
| 4 | PowerPoint: ICE Why change? Slides 7 - 12 | Students should take notes from slides • Have students form teams of 4 |
| 5 | JIGSAW: How long will the worlds oil last? | Pass out one page from the reading ”How long Will the World’s Oil last?” to each team. • Each team reads their portion of the article and writes a summary to share out to the rest of the class • Optional related articles Life After the Oil Crash How Much Oil is Left in the World How much oil is left? |
| 6 | Final project introduction and homework | • Introduce final project: hand out project overview & rubric • If there is time have students begin brainstorming and researching for final presentation Independent Assignment: HOMEWORK •Use the following links to learn about what happened to electric cars. • Write a brief summary • What is your own opinion on why the electric car was “killed”?

| Materials | |
| Will vary from school to school. A Hoffman set up is best for electrolysis, but not necessary. If you are doing the fuel cell lab, day 4, I recommend using the same electrolysis set up. Following are a couple suggested types of electrolysis set ups and fuel cell kits | |
| Basic electrolysis set up | Fuel cell kits |
|

| 1 | Demonstration | Light a wood splint on fire and let it burn for a couple seconds then submerge it in a beaker of water.
Quick write prompt:
|
| 2 | Think, Pair and Share | Students think and write their own opinions in their science notebook. They pair with a partner and add any new information. Each pair shares to the class. Students then add any new information to their notebooks.
Prompt: What & where is HYDROGEN? After the pairs share, show Slide 2 and discuss the listed characteristics. |
| 3 | Chemical formulas for hydrogen production | Show Slide 3. Write the following word forms of the reactions from 1, 2, 3 on the board, have students attempt to write balanced chemical equations. After a few minutes show slides 4, 5 & 6 discussing each reaction. |
| 4 | Video | Show video of solar electrolysis: Slide 7 Gas Hydrogen from Water Electrolysis |
| 5 | Quick write prompt | What is the significance of using solar power to produce hydrogen instead of electricity from the grid? |
| 6 | Electrolysis Lab | Note Follow the directions for proper usage and set up of your own specific equipment. Use of electrolytes such as KOH or HsSO4 act to speed the decomposition of water, but do add safety issues. The procedures, calculations and questions on the Electrolysis lab analysis can be used for most electrolysis setups. |
| 7 | Use the Electrolysis Lab page to label the parts of the electrolyzer. Draw your own equipment set up, and label it, if it is drastically different than the given example. | |
| 8 | Run the electrolysis experiment to collect hydrogen and oxygen gasses. | |
| 9 | Answer the questions and conduct the procedures on the Electrolysis Lab Page. | |
| 10 | Cathode Reduction Reaction | Show Slide 8. Have students draw a picture that represents the reaction that takes place at the cathode. Use the notes from the PowerPoint slide as a verbal description of the reaction. |
